    Great app Just installed for WhatsApp only and it works well. I'm using a pattern. Once the phone is locked it resets. Does exactly what I want. My setting already doesn't preview my message, do this is not an issue

    the app is great. but my moron friend put a pattern and forgot it, and now I can't access to uninstall any apps. When I click on "Forgot?", it asks about my grandma's name but I have no idea what I put in previously. Would somebody help me out?

    My only problem is that even when I lock messenger for example, the notifications are still shown and when a new message pops up you can enter messenger, the message is also shown on the notification bar. I don't know how to fix that..

    I love the app locker, since my sisters always delete my apps, now I don't have to worry 'bout it anymore, it also includes junk cleaner, notifications cleaner and such. TDLR; I HIGHLY recommed this app if you don't want your apps to be deleted or better privacy
